Abstract: 722,879. Electric fires. GREEN, W. H. April 23, 1953 [Feb. 5, 1953], No. 3244/53. Class 39 (3). An electric fire has one or more wire-wound heating elements 39 enclosed in refractory insulating sheaths 42 carried at their ends by hollow refractory insulating brackets 44 secured to a support, e.g. a reflector 17, leads from the elements 39, or continuations of the wire 41 thereof, being led through the brackets 44 and through holes in the reflector 17. The fire comprises end plates 10, 11 screwed together at 14, upper and lower curved cross walls 15, 16, and louvres 31 angularly adjustable about their longitudinal axes by a knob 38. Air entering the bottom of the fire can pass on both sides of the reflector, either through apertures 20, between the top 22 of the reflector and the bottom of the wall 15, and out by apertures 23, or between the reflector and a back plate, leaving again at 23.

Title: An improved vacuum distillation process and apparatus
IPC: B01D3/10
Filed: 1943-03-02
Abstract: 569,105. High-vacuum distillation apparatus; film evaporators. DISTILLATION PRODUCTS, Inc. March 2, 1943, No. 3393. Convention date, June 1, 1942. [Class 32] High-vacuum distillation apparatus comprises a closed still 6 with opposed distillation and condensing' surfaces 18, 10 and a plurality of radial vanes arranged therebetween obliquely in respect to the vaporizing surface and with a relative rotary movement thereto. The rotary vaporizing plate is provided with a centrally formed cup 20 to which the liquid to be vaporized is fed through line 36, unevaporated liquid being flung into a gutter 30 and removed through pipe 32. The vapours pass upwardly through the rotating vanes which are so positioned and move in such direction that the edges of the vanes nearest the vaporizing surfaces are the leading edges in respect to the direction of rotation. Vapours are thus condensed on the side of the vanes remote from the vaporizing surface and the condensate is flung into the space between the flanges 50, 52 and withdrawn through conduit 54. The residual vapours are then condensed on the surface 10 and collected in gutter 56. In the modified form of still shown in Fig. 4, a plurality of fixed vanes 112, 114, 116, 118 are arranged obliquely in respect to the vaporizing surface 18 and are provided with rotating members 96, 98, 100therebetween. The members comprise obliquely arranged vanes 108, Fig. 6, connected to a central hub 102 provided with perforations 110 which lead condensate from one vane to another.

Title: Improvements relating to Electric Arc Furnaces.
Inventor: MOORE WILLIAM ENOCH
IPC: H05B7/00
Filed: 1919-02-13
Abstract: 136,034. Moore, W. E. Feb. 13, 1919. Electrode furnaces.- In a polyphase arc furnace suitable for the manufacture of steel and its alloys, a hearth is connectible to different points along one of the transformer secondaries feeding the upper electrodes, so that the electric pressures of the arcs can be unbalanced and current directed through the bath. In one arrangement, a switch arm S connected to the hearth engages contacts 16 connected to the star point of three secondaries and to points along one secondary f. Further variation in the currents can be obtained by adjusting the electrodes to produce arcs of unequal lengths, with equal or unequal pressures. In another arrangement, four upper electrodes are connected to the terminals of two transformers converting 3-phase into 2-phase currents, and the hearth is connected to two switch arms moving over contacts connected to central and eccentric points along the secondaries. In either case, the hearth 3 may consist of magnesite, dolomite, chromite, or ganister, with an outer layer 4 of refractory material mixed with a conductor such as carbon, the conductivity preferably increasing towards the bottom.

IPC: C08G69/30
Filed: 1961-02-01
Abstract: In a process for the production of a linear condensation polymer by interfacial reaction between a diamine and a bifunctional comonomer with the formation of a hydrogen halide, the free diamine is used in an aqueous medium containing as acid-binder, in an amount sufficient to neutralise all the hydrogen halide formed, a metal compound of negligible solubility in the comonomer phase and soluble but to no greater extent than 0.1% in water so that at all times during the reaction it is dissolved in the acqueous medium in an amount which is substantially less than is sufficient to neutralise all the hydrogen halide.  Specified acid-binders are magnesium oxide, magnesium hydroxide, magnesium carbonate and barium carbonate. Many diamines and dicarboxylic acid halides are specified.  Other comonomers specified are the bis(haloformates) of dihydric alcohols, carbonyl halides e.g. phosgene and disulphonic acid halides e.g. m-benzene sulphonyl halides.  Many solvents for the dicarboxylic acid dihalides are specified.

The ratchet wheel is mounted on a spindle i which carries a crank arm n connected by links o, p<1> to the armatures q<1>, q<2> of the electromagnets s<1>, s<2>. The roller contacts f, m co-operate with brushes n .. t to effect selection of anv one or a combination of circuits in response to a predetermined number of impulses received by the electromagnets s<1>, s<2>. Upon receipt of an impulse the ratchet wheel is rotated by the crank arm and through the pawl d<1> drives the gear wheel a<3> which rotates the roller contacts. At the end of the impulse the ratchet wheel restores to normal. In order to prevent over-running of the roller contacts a cam u mounted on the spindle i operates a pawl j into engagement with a ratchet d when the spindle is rotated. Instead of a pair of electromagnets and armatures a single coil and armature may be employed ; moreover a single roller contact may be employed.

Abstract: 1,165,262. Exchange systems. INTERNATIONAL BUSINESS MACHINES CORP. 26 Jan., 1967 [28 Jan., 1966], No. 4003/67. Heading H4K. In a telephone system in which certain calls between subscribers are intercepted, the number of each called subscriber is identified and applied to a unit (talking machine) which transmits a corresponding audible response to the calling subscriber. The arrangement described co-operates with a known telephone system in which calls which cannot be made are intercepted, and is arranged to receive and process these calls, informing the calling subscriber as to the reason why his call cannot be made. The intercepted calls are applied to incoming trunks 60. The trunks are scanned by a scanner 61 which stops when a call is detected. For most such calls the common control 62 determines whether a connection through a concentrator 65 to an audio response unit trunk 66 and a calling number indicating operator position 67 is possible. If this is not possible the scanner is forced on and the call dealt with during a subsequent cycle. The connection if possible is made and an operator asks the calling subscriber the number he was calling and keys this into the trunk 66. The trunk connects to an audio response system as described in Specification 977,917. This includes a magnetic drum on which data relating to various subscribers is stored. If data relating to the called number is stored a spoken message from the drum is transmitted to the calling subscriber. If no such data is stored or if the subscriber remains off hook for a predetermined period after he has received a spoken message the call is connected to a special operator position 76 via the concentrator 65 and an intercept trunk 75. The operator can speak to the subscriber and give assistance in the usual way and is provided with a keyboard which through an enquiry trunk 77, functioning similar to an incoming trunk, can again interrogate the audio response system as to the spoken message transmitted. The enquiry trunk has an additional line signifying it is from a special operator and an abbreviated or coded message is generated. The called number identification operators 67 could be replaced by automatic means including a buffer store for received dialling signals and analog to digital converters to provide key signals. Some incoming calls may if they include an appropriate indication be connected directly to a special operator.
